Once again, you misrepresent what I've said with these prepared responses based on bias and prejudices that you can't seem to put aside to have a direct conversation with someone. Must I speak to you through your own cultural lense, and handicap myself severely in order to evoke a non-cookie cutter response?
You neglect the concepts of wisdom and knowledge in favor of responding to the flavor of my initial post, which was a snapshot from a manga of which I asked what people thought of the principles outlined. I also explained that I already held the principles in my mind prior to seeing them in the manga. You seem to be responding to an imagined nostalgic and naive emotional charge rather than look at what I'm saying explicitly. Physics do indeed exist, but their application to the human body is simplistic and unsophisticated in the context of training and combat.
